Rectal injection device and method of operation thereof

Abstract

A rectal injection device and a method of operating a rectal injection device. In one embodiment, the device includes: (1) a handle having a trigger associated therewith, (2) an extension tube extending from the handle and terminating in a head, (3) at least two needles coupled to the head and configured to move relative thereto between a retracted position and a deployed position and (4) a pullrod coupling the trigger and the needles and configured to cause the needles to move.

What is claimed is: 
     
       1. A rectal injection device, comprising:
 a handle having a trigger associated therewith; 
 an extension tube extending from said handle and terminating in a head; 
 at least two needles coupled to said head and configured to move relative thereto between a retracted position and a deployed position; and a pullrod coupling said trigger and said needles and configured to cause said needles to move; wherein said needles move toward said handle as said needles move from said retracted position and said deployed position. 
 
     
     
       2. The device as recited in  claim 1  wherein a surface of said head is configured to seat on an anal dentate of a rectum. 
     
     
       3. The device as recited in  claim 1  wherein said needles are evenly spaced within said head. 
     
     
       4. The device as recited in  claim 1  further comprising a needle extension indicator associated with said handle. 
     
     
       5. The device as recited in  claim 1  further comprising an auto injection button associated with said handle. 
     
     
       6. The device as recited in  claim 1  further comprising an injection complete indicator associated with said handle. 
     
     
       7. The device as recited in  claim 1  further comprising an internal device syringe associated with said handle. 
     
     
       8. The device as recited in  claim 1  wherein said head is of larger diameter than said extension tube. 
     
     
       9. The device as recited in  claim 1  further comprising a Luer activated fill port associated with said handle. 
     
     
       10. A rectal injection device, comprising:
 an elongated handle having a trigger coupled thereto; 
 an internal device syringe located within said handle; 
 an extension tube extending from said handle and terminating in a head configured to seat on an anal dentate of a rectum; 
 at least three needles evenly spaced within said head and configured to move toward said handle from a retracted position to a deployed position; 
 a pullrod coupling said trigger and said needles and configured to cause said needles to move; 
 a needle extension indicator associated with said handle; and 
 an injection complete indicator associated with said handle.
